96 The Partridge Family 



THE CHESTNUT-BELLIED SCALED PARTRIDGE 

 (C. s. castaneigastrd) 



This is a subspecies of the preceding, distin- 

 guished by a more or less extensive patch of 

 chestnut on the belly. With this exception, its 

 habits, color, and markings so closely resemble 

 the other that further references are unnecessary. 

 It is found in the lower Rio Grande Valley, in 

 Texas, and in eastern Mexico. From the sport- 

 ing point of view, it has little to recommend it.
